A, you combine like terms.
a) 11n-4+n+12
11n+n=12n
-4+12=8
12n+8
Answer: 123
Step-by-step explanation: TO solve problems like this, you should assign a variable to the lowest number, lets just say n. From here, since we know the numbers are consecutive, we can see that the numbers are n, n+1, and n+2. Therefore:
n(first number) + (n+1)(second number) +(n+2) (3rd number) =366
>n+n+1+n+2=366
3n+3=366
3n=363
n=121
n+2=123
Answer:
<em>m∠2 = 47° </em>
Step-by-step explanation:
m∠1 + m∠2 = 90°
3x + 13 + 5x - 3 = 90
8x + 10 = 90 ⇒ x = 10
<em>m∠2 = 47°</em>
128 is the total amount. Because she has megabytes negative
Answer:
$3,078.00
Step-by-step explanation:
A = $3,078.00
(I = A - P = $378.00)
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year.
Solving our equation:
A = 2700(1 + (0.07 × 2)) = 3078
A = $3,078.00
The total amount accrued, principal plus interest, from simple interest on a principal of $2,700.00 at a rate of 7% per year for 2 years is $3,078.00.
